IMPROVEMENT IN CAR-BRAKES.

Specification forming part of Letters Patent No. 144,787-, datedNovember 18, 1873; application led June 25, 1873.

I To all whom it may concern:

Be it known that l, .Timms B. PELTON, of Mount. Pleasant, in the countyof Frederick and State of Maryland, have invented a new and ImprovedCar-Brake; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawing forming part of this specification, in which-Figure l is a plan; Fig. 2, a longitudinal sectional elevation; Figs. 3,4, and 5, detail views.

The invention relates to that class of brakes which are `operated bysteam from the locomotive. It consists in the mode of providing the cordwith a take-up mechanism, by means of a tube and pnlley-frame, jointedso as to fold up when the trucks come close together and to unfold asthey separate, thereby maintain- I ing a constant tautness in the cordwhich connects the power with the brake mechanism, and preventing thebrakes from being applied unintentionally. It also consists in the modeof forming the tube in two parts, jointedl so that one can be turned upon the locomotive when not in use. It also consists in connecting thepower mechanism and brake-bar mechanism with the intermediateactuatinglever on both sides of its fulcrum, so that, no matter onVenabling the slack of the cord to be taken up, whether the trucks arejammed up together, as when the train stops, or extended, as when thetrain is in motion. C1 O2 is a two-part tube, which allows the part G2to be turned up on the locomotive when not in use. This cord now passesover apulley, c, and then connects with a rod, E, that is pivoted toaplate, F, on the brake-operating lever G. The latter is fulcrumed at g,and connected from two points, g1 g1, and by two sets of chains, cords,or rods, g2 g2, with the rods H H2, that operate the lever H1 of thebrake-bars I J By this construction, when the cars 'are operated fromeither direction, the brake is actuated with equal facility and in thesame way.

I am aware that twotoggle-arms, one attached to each adjacent car, havebeen used as a pulley-frame and tension device; but theyY are in the waybetween the platforms, and require to be taken apart; while my tube andpulley-frame are attached only to one car, extend over the platforms andnot between them, the tube having the advantage of preventing anyinterference with the chain.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The tube C, jointed to a pulley-frame, D, and extending over theplatforms of two adjacent cars, all combined as and for the purposedescribed.

2. The tension -tube C, made in two hinged sections, to fold back on thecar towhich it is attached when not in use, combined as and for thepurpose described.
